Error: [undefined] is not a <Route> component. All component children of <Routes> must be a <Route> or <React.Fragment>

Question

我正在尝试将 react-router-dom 从 v5 升级到 v6，但我收到此错误消息。

Error: [undefined] is not a <Route> component. All component children of <Routes> must be a <Route> or <React.Fragment>

任何人都可以帮助我解决这个问题。

ReactDOM.render(

您应该将组件作为“元素”传递，例如：

<Route path="/" element={<Dashboard/>}>

或者对于受保护的路由：

<Route
 path="home"
 element={
   <ProtectedRoute user={user}>
   <Home />
   </ProtectedRoute>
      }
    />
    ...
  </Routes>
